Как сделать solution explorer в С#?

treeView1.Items.Clear();

private void GetFiles(string path, TreeViewItem parent)
{

  }
  else
  {
    parent.Items.Add(node);
  }

  var attr = System.IO.File.GetAttributes(path);

  if (attr.HasFlag(System.IO.FileAttributes.Directory))
  {
    var directories = System.IO.Directory.GetDirectories(path);

    foreach (var dir in directories)
    {
      GetFiles(dir, node);
    }

    var files = System.IO.Directory.GetFiles(path);

    foreach (var file in files)
    {
      node.Items.Add(System.IO.Path.GetFileName(file));
    }
  }
}
